- To all whom it may concern:

Be it known that I, CHARLES SCOLE, a

new and useful Improvements in Gasolene- .'ngines, ofwhich the following is a specification.

My invention relates to motors or engines and more especially to thatv` class known as gasolene engines, and is ofthe same general type as that shown in my lprior patent wzaacidated March 31st, .loca

The invention further consists of certain g improvements upon the abovetype of machmes `which will better adapt itvto the use of gasolene, and insure improved results. l

The engine is especially designed for automobile use and wouldy preferablybe operated. in a series of two or more, but is obviously equally practical vforother uses, as Vfor instance motor cycles, launches, andlikewise stationary work.

It is the objects of m invention to simplify, cheapen and genera ly improve the construction of engines ofl this class; to include an improved form of combined ported piston and valve for controlling the supply of fuel to the cylinder in a way to startor stop the engine, or to operate it in either a forward or backward direction; to provide a reciprocating fuel chamber, with means for introduc-` ing fuel thereto, and having suitable ports for passingsaid fuel into a combustion chamber, where it is fired in a way to operate the piston and crank shaft, and finally to provide means for exhausting the exploded products into the atmosphere.

With the above objects in view my inventionr resides and consists in thevno-vel construction and combination of parts shown upon the accompanying two sheets of drawings forming a part of this specification, upon which simi ar characters of reference denote like or corresponding parts throughout the several figures and of which Figure 1, is a central vertical longitudinal sectional view through my improved engine, showing the cylinder, piston, connecting rod, engine shaft, etc. Fig. 2, is a similar section of my engine with the piston and other movable parts ina different position. Fig. 3, showsa cross sectional plan view of the cylinder and piston taken on line 3--8 of 'y Fig. 2 and as if the mixing chamber 'and valve were remo'yed. Fig. 4, is asimilar and rod 13 movably mounted therein.

as by means of bolts 20, and adapte sectional. plan view of the piston.' 16v taken-on line 4Q-4 of Fig. and asseen from the lcitizen of the United States, and resident of i opposite direction of'Fig. 3. 5, is a dey Bridgeport, 1n the county of Fairfield and tached perspective view of the :State of Connecticut, have invented certain valve seated co in the piston, for controlling the operation of the engine, and Fig. 6, is a detail section of a portion of piston and connecting rod as seen in Figs. l and 2,.but with rod in different position. y

Referring in detail to thecharacters of reference vemployed to designate the corresponding parts in the several figures of the drawings, 10 represents the engine body which as shown may be. preferably formed in two'parts and 70 secured together as by means of bolts. 11 is a chamber, within the lower part of bodyT to accommodate the crank shaft 12 This chamber also serves as a receiver 'for fuel, 75 which is introduced from and through any suitable source, as for instance a pipe 14.

15 indicates a cylinder that is arranged at a right angle to the crank shaft and is preferably formed integral with the upper part of engine body, which is bored to receive a. reciprocating piston 16 that is pivotally connected with the crank rod 13 bylmeans of av pin 17. A second and smaller cylinder 18 isformed in the extreme upper reduced end of the body having its lower end portion extending down into the before mentioned piston cylinder. This smaller cylinder 1.8 is 1n alinement with the larger cylinder and serves to form a gui-deway for a cylindrical mixing chamber 19 secured to the Cpiston 16 to reciprocate therewith.

The piston comprises a cylindrical body 15 fitted to reciprocate in the bore of the cylin- 95 der and having an internal flange 21 formin a shoulder against which a head 22 .ttev within the upper end ot iston, is seated. This head may be secured4 1n place by means of the before meirtiried bolts 20 and con- 100 tainsa semici'rcular recess 23 upon under side, against which the transverse cylindrical ond portion 24 of rod is iitted. This end is provided with pockets 25 and 26 upon opposite sides, which aredcsigned to cominunicate with the ports 27 and 28 to pass charges of fuel therethrough from the fuel chamber 11 to the mixing chamber 19. Within the top of lthe head 22 is formed a circular recess 2u the annular portion Vof 110 whichis covered by flange 30 of the cylinder 19. l `Within this recess is fitted a disk valve to register with either of the ports 27 lor 28. 'This valve is provided with a central shoull 31 designed to be 'rotated therein and having a port 32 therethrough that may be adjusted .dered stem33 by meansof which Ait is rotated to shift t e position o f the'said port 32 .with'grelation to the ports 27 and 28 in a mannerito openr and' close the same. The said stem 330i valve'is slidabl fitted in a shouldered tube 34 in a way to e operated thereby, and is rotated therein. The tube is provided with a rounded end portion jourf Analed in a bearing in'end. of smaller cylinder A10 and is provided with a suitable handle 35 by means of which it may be manually operated from the exterior of engine, to operate the same. On opposite sides ofthe upper portion of the reciprocating mixing chamber 19 is provided ports`36 which register with similarly located ports 37 in o posite sides of the upper and smaller cylin ers 18 which -ports when communicating admit cold air from the exterior to the mixin chamber. This air is thus obviously intro u ced when the piston and connected ports are in their uppermost position and whenrthe previously introducedcharge isbeing compressed within the combustion chamber 38. These ports 36 are also designed to register with ports 39 in lower part of cylinder-to pass the mixture fromv mixing chamberl to the combustion chamber 38, when piston is .in lowered position or at end'of stroke. When the piston is in the above position it will have uncovered the exhaust ports 4() so as to'.allow the exploded gases Ato escape from the cylinder, causing a vacuum therein that insures the mixture quickly entering the cylinder through'the ports 36 and 37 before described.

The. operation of my improved gas engine with the controlling valve set as shown in the drawings is as follows z-l/Vith the downward travel of the piston and the connected operation of' the crank shaft 12 caused by the ex plosion of fuel in chamber 3,8', the rod 13 is rocked to and from the position Shown in Fig. 6, in a way to admit 'a charge of fuel from the. chamber 11,through the ports 26 and 32 to the chamber 19 where the fuel may be further mixed with previously introduced cold air. When the nected parts reach the end o th'e downward stroke the orts 36 will register with the ports 39 as s own in Fig. 2, ina way to allow the mixture to escape into the firing chamber 38. The return movement of the piston obviously tends to com ress the mixture in the firing chamber w ich becomes verymuch reduced in area as shown in Fig. 1, and smaller than the interior of th'e mixing chamber. While in this position the charge is fired in the usual way and through the introduction bf'a spark xoduced in part by the plug 41 which ex lbsion drives the iston down to the end of) the stroke where' t e existon and conhaust escapes through the ports 4U, .Simul-q 'taneously with the firing as just explained the before mentioned ports 36 and 37' are in alinement, to admit a small quantity of cold air into the chamber as before referred to. 7

The foregoing operation applies to the forward drive of the engine, that is in directioir' of arrow shown in lfig. .1, and includes thel use of the ports 26 and 28. It will be apparent however, .that a reversal of the engine, 7 would be obtained by a reverse positive rotation of the engine in a reverse direction after the valve -had been reversed-which. is effected through a half turn of the handle 35 which means the .shifting of the port 32 from above the port 28 to above the port 27 on op'posite si e. This movement of the valve permits the fuel to come up through the ports 25 and 27 on the opposite side during the downward movement' of the piston. It s is also possible by shifting this .valve to an intermediate position, to cut off 'both partel in a way to stop the engine entirely'. It will therefore be seen that the engine is entirely controlled by the valve and requires but the 9 usual preliminary positive rotating'to start or reverse it and can be driven forward or backward fast or slow as occasion may require.
